I developed Lichen Planus and Sclerosis after my second confirmed Covid infection. (Literally, the second day of illness both areas exploded.) Having no clue, and in the middle of switching to a new doctor, I went from September to end December untreated, and was very bad when diagnosed. I had been experimenting with a full red light blanket for long covid, and my mouth started to heal first. I found a cheap ($30) red light belt on Temu and Amazon rated for red and UV light. I turn that belt into a circle with the velcro...put it at the highest setting for 20 minutes 3x/week, and it has gone into remission. It only comes back slightly when migraines prevent me from remembering to treat it. It also works beautifully on the lichen sclerosis(vaginal). I open the belt and lay it front to back on the closed lid of the toilet. I put a couple of layers of toilet paper on it and straddle the belt on highest setting for 30 minutes 3x/week. I hope this is able to help someone.
